So sorry about this. I hate to see cases like this because your smile is the first thing noticed about you, it is the basis for your approachability, success, emotions. "In an instant your smile can say everything that is good about you." - Ivanism It is clear the proportionality is off with these front teeth and proper planning of this case is highly recommended by an experienced, highly trained cosmetic dentist. As you know, there is no cosmetic specialty in dentistry, though there should be, and so you have to do your homework to find the best professional for your most important front teeth and smile. To often patients don't know who is equipped with the skills and training to do this important work and they use subjective criteria such as "the dentist was nice and he charged less than that other dentist" rather than really know who is competent. I don't need to tell you that if you are going to have 6 veneers done, which is highly not recommended by highly experienced and trained cosmetic dentists, then you have to understand materials, shading very well. I usually don't like to do six, but if I do them, it is critical to match them to your natural teeth posterior to the last veneer. But this is certainly the least of your concerns. when dealing with crooked, crowded or overlapping teeth, it's even more incumbent to be highly trained in cosmetic dentistry. If you have lost space, how do you make teeth look straight? In addition, the gums are usually at different heights when there's crooked teeth and you have to make sure you accommodate for this. If you ask me this is the major cosmetic issue, among several, that adversely affects your veneers. The "black triangle" is also a consequence of not accommodating for a crooked tooth being straightened in a veneer case. So unfortunately your smile might attract attention in a way you did not intend. I am so sorry to say that this case reflects perhaps a lack of experience or training in these cosmetic situations. The gum incongruency, even the differing shades of the two front teeth, changing the contours of your natural teeth in the veneers and not doing enough teeth, might be attracting attention in the wrong way. If you are only going to do 6 front teeth, which I might venture to say most highly trained cosmetic dentists would not do, then you have to match them up better to the patient's natural teeth. No one smile width goes only 6 teeth. So these 6 teeth must match up to your natural teeth. In this case the 6 front teeth are different in shape, contours, shade, value and hue, and overall size and shape. They will look artificial and not blend in well with your overall smile. Sorry if I am being critical but this is why it is imperative to choose your professional well by training, experience, examples, photography, website results, and not based on just a "nice guy" or cost. You may not get a second chance to do the job right. Now that I have stated the problem, what's the solution? You may have to redo these veneers by someone who is highly competent in cosmetic dentistry and has significant experience and training, with some credentials in cosmetic dentistry. I would definitely change the two front teeth, do gum recontouring procedures and pray you can match the two front teeth to the the other four. Not easy, but maybe worth a try before tossing the whole case out and redoing them all correctly. Sorry for that poor prognosis. Best, Dr. Ivan
